Take a Deep Breath

Many Zenit cameras were supplied with a Helios-44 lens of 58mm focal length and a maximum aperture of f/2. This lens was a Soviet copy of the Carl Zeiss Biotar lens and had distinctive bokeh characteristics. So Helios = Zeiss. Possibly.
This photograph was made with one of the original Helios-44 lenses from the KMZ factory - not one with -2, -3, -4 or M after the "Helios-44". It has a preset diaphragm where aperture adjustments are made at the front. The handling is dreadful. But the results are rewarding, save for the high rate of attrition through bad focusing and wrong exposure (both being my fault, not the fault of the lens).
